How does XDR transfer data?

When synchronizing data between data centers using Aerospike XDR, how is the data transfered? Do the same number of nodes need to be in each data center?

When using Aerospike XDR, the simplified view is that there are 2 clusters in 2 data centers, the local and the remote. Each node in the local data center acts as a client to the remote data center. As a result the configuration of the two clusters do not have to be the same. They may have different numbers of nodes and different hardware.
